Uniden produces a wide array of phones such as the Uniden CEZAI998 series with large, easy-to-read displays, well-spaced buttons, and sound amplification for the hearing impaired. Every once in a while, one of these phones will have a problem, and you may need to do some troubleshooting.
Not getting a dial tone
For the cordless models of the Uniden Ceza series, the first thing to check is to see if the handset lights up when you pick it up. If not, there is a good chance the battery needs to charge. If the handset does light up and you still do not receive a dial tone, check the charger base and make sure it is plugged into the phone jack as well as the power supply. If this still does not work, contact your telephone provider about an interruption in your service.
Excessive Line Noise
Hit the talk button on the hand set without dialing a phone number, see if you are receiving line noise without actually dialing someone. If so, try again closer to the charger station. Many times walls and magnetic waves in the 2.4-plus GHz range can interfere with reception. If you are still experiencing problems without dialing, then your handset may be damaged. If you only receive line noise during a call, check the distance to your charger again. If that does not clear it up, then contact your telephone provider about fixing your phone service.
This by far is the most common complaint by Uniden Ceza users. The first step is to make sure that your battery is fully charged (on the handset there are five bars on the LCD screen, make sure you have at least three darkened bars indicating a charge). If that does not solve the problem, check the distance to your charge station. Moving out of range of the receiver can cause line noise and call loss. If these do not solve your problems, contact your telephone provider for service.
